I've been calling this newfound knowledge of mine a feetish.
I will admit, there is nothing quite like a good foot massage. I don't get them, but being the prince that I am, I do have a half-baked foot massager that sits under my desk. I turn it off during video calls so no one sees me drooling and making happy noises and finding themselves wondering why.
I also got mine, and I was using it while working earlier - I do hear you!
Seems like u got very serious about your discovery :D
